Owners of 2012-2014 Cadillac Escalades may complain of unwanted grade braking when not going down a grade, reduced engine power with no DIC messages (or DTCs) and transmission busy/frequent up-down shifts.

These issues may be caused by the brake pedal position (BPP) sensor not being learned correctly in the ECM.

With the brake pedal released, use the BPP sensor parameters to determine if the ECM has learned the BPP released position correctly. If the BPP sensor learned released position voltage does not match the BPP sensor voltage with the pedal in the released position, the ECM will need to have a BPP relearn performed.

If the ECM will not perform a BPP sensor relearn, use the Tech 2 to verify that the BPP sensor is now showing 0% with the brake pedal released.
